I have a 1.1.4 OTB iphone that i'm currently using with AT&T and recently jailbroke it using ZiPhone and it was working great for 3 weeks until today when out of nowhere it gave me an error saying your iphone is unable to make/receive calls and you must contact Apple Support. So I went and tried to restore through iTunes and it will not restore it gives me an unknown error 1003 so I tried re-jailbreaking through ZiPhone and it worked and I was able to make/receive for a few hours and now its doing the same thing again. I just want to get this back working to the state it was out of the box. Also now when I go into about the phone it doesn't recognize the baseband or IMEI information once its crashed. Any help would be greatly appreciated thanks.
